It preferred, the air-supply inlet-tap of the nozzle may be dispensed with, especially in the compound nozzle last described. By this improved arrangement as the level of the fluid to be sprayed and the pressure of the air are constant. any desired fineness of spray can be produced and maintained when once the delivery of the nozzle has been adjusted and no dripping or dropping of fluid from the nozzle will take place.

I do not claim, broadly, the forcing of fluid to a nozzle by the air which makes the spray; but

What I do claim is- 1. The combination of a spraying-nozzle or series of nozzles with means for supplying air under pressure from a suitable source and means for maintaining the fluid to be sprayed at a certain level in the supply-pipes, so that when once the delivery of the nozzle has been adjusted the spray will be perfectly maintained without dripping of the fluid as the level of the fluid and the pressure of the air are kept constant.

2. The nozzle consisting of the combination of internal and external tubes, the regulating tap or taps in connection therewith, and the adjustable nozzle packed and sliding on the external tube so that the spray can be kept at a desired state of fineness, although the amount of fluid ejected from the nozzle may be Varied.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

A. G. BROWNING.
